LIBRARY OF THE GERMAN PATENT OFFICE

The invention relates to a method and a device for pushing or applying of rows of stitches or double crochets of one or more knitted fabric edges on top of one another on needle threads, especially for linking on linking machines. The aim is to achieve the objective of preventing belching facilitate and the device developed for it more powerful than the previous facilities and to simplify the production of linked knitted goods.

For chaining seams on knitted fabrics, for maintaining the seam edge and for feeding them to the Sewing or linking tools of the linking machines facilities known, which essentially consist of a partially equipped, on the whole movable, straight or circular row of needles (needle contour) exist, on whose needle parts protruding from the bed of the fontur the stitches to be linked Edges are pushed open by hand stitch by stitch.

This commonly used way of applying the edges to be linked is laborious and required a lot of patience and skill. In addition, the production of the needle contours is difficult and their use is expensive due to the special pitch-bound feed device.

To facilitate the work of burping by hand, devices have already become known at which z. B. the fabric edges to be chained from a knitting or knitting machine through upstream Auxiliary devices are transferred to the fontur of the linking machines. However, these facilities are suitable only for very special warp inlay and also require several additional special devices.

In order to solve the problem, it is proposed according to the invention that at the beginning of work one end of the goods is pushed onto one or more needles of a font, preferably by hand the further burping takes place automatically by inserting the needles individually or in groups one after the other the following stitches of the knitted fabric edges enter, the already opened fabric stitches one Seam formation point (sewing tool) of a known type are fed and then the needles individually or leave the linked goods automatically in groups one after the other. This is what happens Mechanically inserting the fountain needles into the rows of stitches; by pushing in, the transverse transport causes the preceding needles with the pushed open goods; pulling out the Needles from the linked goods are also done mechanically, the mechanical drives preferably are coupled.

In an arm 1 (Fig. 1 and 3) of a linking machine housing 2 is a U-shaped, from the two side walls 3 and 4 and the device housing 7 consisting of a base plate 5. The arm 1 and thus also the device housing 7 are covered by a cover 8, the can also be used as a table top of the linking machine.

Inside the device housing 7 is a block 9 with its rear end 10 (Fig. 1 and S) screwed to the base plate of the pre-seal housing. The upper front part of the block 9 is cut out (fountain bed 11) and is used for recording a number of needles 12 bent at an angle and standing next to one another (font 6, Fig. 4) - in the present example 30 pieces on two inches - which are carried by plate-like supports 13 (Fig. 6). A second recess 14 under the block 9 takes an equal number of needles equipped adjacent needle carriers 13 (Fig. 1, 2, 3). The lower space 14 serves to a certain extent as a magazine to equip for the fontur 6 lying above this space 14, to which during of linking by a between the block 9 and the Side wall 4 located gap 15 (channel) continuously brought needle carrier to needle carrier and is lined up, while on the other side of the block 9 by one between it and the side wall 3 located space 16 in the same way running one needle carrier after the other the fountain 6 or from the fountain bed 11 is conveyed into the space 14. The two channels 15 and 16 have about the width of a needle carrier. The block 9 is beveled at its front part 9 ', see above that the needles 12 located in the space 14 can stand free with their tips. The fountain bed 11 and the space 14 - are towards the rear (Fig. 5) through a transverse wall 17 each extending over the block or 18 delimited, against which the needle carrier 13 abut with their rear edge 19. The transverse wall 17 of the fountain bed is with reference to Fig. 1 on the left in front of the transverse wall of the room 14, so that the front The end of the font 6 with the needles 12 is free to the front and the belching of the goods is unhindered can be done.

The strength (thickness) of the needles 12 or the needle carrier 13 depends on the mesh division of the linking goods (Fig. 11), so that to equip the fontur 6 and the space 14 the division of the Goods corresponding needles 12 and carriers 13 come to use. Channels 15 and 16 (Fig. 3) are therefore adjustable in width for the passage of the carriers 13, which are different in thickness depending on the division, by attaching spacer plates 20 that can be displaced on shafts 22 on the side walls of the block 9 are; the shafts22 are screwed
